No, I have not seen this problem. Then again, I typically use an AIX
box as my X window machine and run sessions from others back to it.  I
can test the setup you suggest, however, by running a McIDAS-X session
on a variety of other machines with display back to a Linux box.  I
will give this a quick try and let you know what happens.


I ran the following test:

o login onto the system console of a machine running RedHat Linux 6.2
o from there, rlogin to a machine running Solaris x86 2.8
o set DISPLAY back to Linux box
o ran Unidata McIDAS-X 7.7x (includes 7.701 fasttrack)

I saw no weirdness at all running in this mode.  Is it possible that
the user was running a pre-7.7x version of McIDAS?  7.6x's poor
handling of 24-bit visuals would explain Benson's comment "the results
are intolerable".  

For the record, what exactly was intolerable? What version of Linux did
John do the test on?

Ooops.  John was running 7.603.  This was before Rod's 24-bit changes. 
Sorry for the false alarm.  We still need to know what the differences
between our config and our new site's config, so the issue may not be
